QLOUNI 150pcs Mini Twist Drill Bits Set, HSS Shank Drill Bits Kit Micro Twist Drilling Tool Helicoidal for Wood DIY with Storage Box, 0.4mm-3.2mm

I ordered the drill bit set to use in model boat building. Of the smaller sizes, most of the bits we're unsharpened, just cut off as if with wire cutters. A few of the small size bits we're missing altogether. I emailed the supplier, his only response was to read the description in the listing. I returned the whole set for a refund and spent the money on a quality product.

A lot if drill bits. Good range of bits with small steps. The slide thing on the box it comes in broke after a day but it still closes. The quality of the drill bits are not the best. A couple broke within a minute but there were plenty to replace that one. Difficult to see which one is which. If the diameter would be etched on the drillbit it would get 5 stars

A good range of bits, though quite why there's less of the ones that will snap just looking at the piece you're working on I don't know.Also it's kind of difficult to figure out which bit is which. Especially when my youngest daughter was being helpful and dropped them on the floor. Of course the box they come in isn't sturdy enough to withstand a half metre drop and there. Were. Bits. Everywhere.Oh well.Other than that, they cut ok, the smaller ones need a pilot hole before you drill if possible.

A complete waste of money for model making as these bits are blunt and won't initially pierce 10 thou brass or nickel silver sheet. I used the reliable YAKAMOZ high speed steel drills (also available on Amazon) to pierce the hole, then opened it up the gradually using these - it took ages as not one of the sizes included in the QLOUNI drill box was sharp.

Overall the product is OK. It is good value for money for the quantity of drill bits but some of the bits are very blunt. However, they did work with the right amount of pressure applied.

These tiny drill bits are a great set with multiple bits of each size so you can get through a project without the worry of running out of bits. Good for detail work. Box containing bits well thought out with central clasp and clasps on Face of box which are handed so one opens up and the other down. This method stops the bits from mixing together. An additional plastic liner further keeps the bits in their allotted position.

This is a comprehensive set of micro and mini drill bits and plenty of them. The box means they are all separated so you can easily find the size bit you need. Care though when unpacking to make sure they don't get mixed up! Nice sharp bits for model making.

I read a number of bad reviews of this product but I have found it quite good. Perhaps some of the drills are not so sharp but generally I have found them fine for my model wooden boat building. There are plenty of them for the money so overall good value.
